This is how the mod works:

When you type home in the chat, the player is teleported to the designated home position. -
When you type out, the player teleports to the out position.

To start, build yourself a small base, and save the coordinates of that base.

Create a variable, called homePosition, and set it to the coordinates of your base.

Now create another variable, outPosition. When the mod starts, the agent will teleport to the player, and outPosition will be set to the agent's position.

Coding the home and out commands are simple chat commands that will teleport the player to either homePosition or outPosition.

Walk away from your base, and run the mod. Try teleporting back and forth using these commands.

Challenge

Code a chat command called setOutPosition that will reset outPosition. That way, the player can choose exactly where they teleport to next.

Testing the Mod

To test all the aspects of the mod, type the command /locate structure stronghold to get the coordinates of the nearest stronghold. Teleport the player to that position using /tp @s x y z.

Now use setOutPosition from the challenge and set your teleport position to the stronghold. Teleport back and forth between the stronghold and your base. If you can get a result like in the video below, you've completed the mod correctly.
